Use this guide to replace the battery in your Samsung Galaxy S9.

Opening the Samsung Galaxy S9 will damage the waterproof seals on the device. If you do not replace the adhesive seals, your phone will function normally, but will lose its water protection.

Before disassembling your phone, discharge the battery below 25%. If your battery is swollen, do not heat your phone. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.

You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Before you begin, switch off your phone.
    • Before you begin, switch off your phone.

    • Apply a heated iOpener to a long edge of the phone to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes.

    • You might need to reheat and reapply the iOpener several times during the removal procedure to get the adhesive warm enough to cut. Follow the iOpener instructions to avoid overheating.

    • The adhesive of the Samsung Galaxy S9 is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    Nightmare. Impossible to get the back off so far. Being trying using the iOpener with hair dryer for last 1hr. No chance.

    You’re right Chris. I’ve tried on 3 separate occasions now and haven’t been able to budge that back. All that has happened is the pick has taken a piece out of the glass back leaving a rough edge now.

    it was not easy but doable.

    It’s difficult, but the trick I did to get it was to wrap the hot iOpener around a bottom corner, apply the suction cup, then I covered the opener and phone with a paper plate, better insulating the area. Then I set my blow dryer to high heat and low velocity and heated the area under the plate for about a minute. Right after turning off the blower, I took off the plate and pulled the suction cup with a cutter at hand. You’ll hear a bit of a cracking/popping noise when the adhesive is starting to give, just apply a little more force and push the cutter at the seam. This method worked great for me, so good luck and just keep at it — you’ve got this!

    I used nearly boiling water in a storage zip bag on the phone for 10 minutes. I can’t really recommend this method, but thankfully the bag did not leak - an iOpener is probably a much better way to go. Regardless, the bag covered the entire back of the phone, and the phone was too hot to hold, but I still could not get the glass to budge with the suction cup after struggling with it for about an hour and multiple reheats. I ended up epoxying a 2”x2” square of PVC board to the bottom of the cover and built a relatively complex fixture that pulled on the PVC with the turn of a screw while it held down the frame by the edges. After heating the edges up again It did lift the glass enough to get a pick underneath it, but it cracked the glass and it was a pain to slide a pick around the edge while the glass was cracking all the way around. Once I finally got all the glass off, I spent the next 30 minutes (which is what this entire process is supposed to take… what a joke!) cleaning the adhesive off the phone.

    Heavy Duty Heat Gun from popular discount tool store for the win!

    Jesse Meyer - 답글

    Well, it is not obvious how to do this. I have no iOpener, but a heat cushion for remedy hurting muscles and sometimes a backpain. It is filled with grain of some kind and it is to be heated in a microwave oven for about 3 minutes. After that I enveloped this cushion round the phone and brewed myself a cup of tea. After ten miutes the phone was warm (almost hot) and I was able to press the tip of a small (very small) knife above the charging port into the connection between the phone body and the backplate. A very small opening emerged slowly (this is the critical point in this process) and I was able to start using the iFixit opening picks. It became obvious to me that the opening picks are too blunt to achive this with them. But after starting carefully with the (very small and very sharp) knife, everything went straight forward. Thou I had to give the phone a second heatpush with my heat cushion before the backplate came loose.

  2. In the following steps, you'll be cutting through the adhesive securing the back cover.
    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive in the inside of the back cover is laid out as seen in the image.

    • You'll be slicing through the adhesive in the areas shown:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying or slicing in this area, to protect the fingerprint sensor flex cable.

  3. If the phone's rear glass is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed. Press a suction cup onto the back cover. Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

    • Press a suction cup onto the back cover.

    • Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

    • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Insert an opening pick in the gap you created and slide it to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner.

    • Insert a third opening pick to prevent the adhesive from resealing during the rest of the removal procedure.

  4. While inserting only the tip of the opening pick, slide it from the bottom left corner along the side to the top. Slide the pick around the top corner and leave it there to prevent the adhesive from resealing.

    • Slide the pick around the top corner and leave it there to prevent the adhesive from resealing.

  5. Slide the opening pick from the bottom right corner along the side to the top. Apply more heat if the adhesive becomes hard to cut. During the removal process, the back cover is under tension all the time and is likely to break if the adhesive isn't softened enough. Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.

    • Slide the opening pick around the corner and cut the remaining adhesive at the top of the phone.

    • Don't open the phone all the way yet. The fragile fingerprint sensor cable still connects the back cover to the motherboard.

  6. Carefully lift the side of the rear glass where the volume button is located. Use the edge of a spudger to pry up and disconnect the fingerprint sensor flex cable.

    I think the #000 fits better!

    The second and fourth screws on the bottom row are a little shorter at 2mm ( I measure the others as 3mm). Worth some care to put the screws back in the same holes as they came from. (SM-G960U)

    Will Smart - 답글

    Hi Will,

    thank you for mentioning! On our model the “SM-G960XU” all screws have the same length (4 mm). However this might differ between different models and is definitely something to keep an eye on during repairs.

    • Avoid this area. There's a gap in the mid-frame right below the battery, and you can accidentally damage the display through it.

  14. In case you have trouble to pry up the battery the adhesive may not be loose enough. You can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive. Try your best not to deform the battery during the following removal process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

결론

To reassemble your device, follow these instructions in reverse order.

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

For optimal performance, calibrate your newly installed battery: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%

Take your e-waste to an R2 or e-Stewards certified recycler.

Merci ifixit.

Mais je n ais pas compris la deconnection du NFC, es une nappe. Je ne comprends pas.

Di Da - 답글

Bonjour @Di Da, vous trouverez la partie qui parle de la démontage du coque / de la cache en plastique qui abrite l'antenne NFC et la bobine de recharge dans les étapes 9 à 11. Au fait, la cache en plastique et la nappe sont UNE pièce ensemble, on ne peut pas les séparer et dès que vous démontez la cache, la nappe va elle aussi sortir automatiquement. Elle n’est lié que par quelques contacts, vous n’avez pas besoin de déconnecter ceux-ci, ils se séparent automatiquement quand vous retirez la coque.

Wenn nach Abschluss der Reparatur der Fingerabdrucksensor nicht funktioniert muss man in den Restore Modus des Handy gehen.

Dazu das Smartphone an den Lader hängen und das Gerät ausschalten.

Dannach die Bixby + Power + Lauter Taste gedrückt halten bis das Samsung Logo erscheint.

In dem Menü den Punkt “Wipe Cache Partition” auswählen mit Lauter / Leiser und mit Power die Auswahl bestätigen.

Die Auswahl nochmal mit Yes bestätigen und warten bis das Gerät die Cache Partition gelöscht hat und das Gerät neu starten.

Dannach sollte der Fingerabdrucksensor wie gewohnt funktionieren.

Why does the guide stop? How am I supposed to use the adhesive??

Mitchell steindler - 답글

Hi Mitchell,

the last step offers a guide to install an adhesive. Hope that helps. Otherwise, all our guides are “re-assemble in reverse order”.

Tobias Isakeit -

For what parts? There’s multiple sets of adhesive on this device, and I would personally recommend applying the adhesive the same way that it was applied on the original battery.

Kaleb White -

I’ve bought a replacement battery for my S9 to do this but it hasn’t come with any adhesive. Which one(s) do I need any where can I buy it?

danreilly - 답글

Hi danreilly,

in case you don’t want to buy custom cut adhesive for this, you can use regular double sided adhesive tape.

Dominik Schnabelrauch -

Guide was definitely helpful. Having some tips or comments for assembly would be helpful particularly for reattaching the fingerprint sensor. A magnifying lens for the tiny pin connections is recommended.
